Hi,

What does LS age is equal to MaxAge mean exactly and why would I get it over and over again
in a continual stream?

Both my directly connected uplink CISCO's neighbors show as full:
    Neighbor ID Pri State           Dead Time Address         Interface            RXmtL RqstL DBsmL
172.16.10.47      1 Full/DROther      35.462s 10.255.14.29    gre2:10.255.14.30        1     0     0
172.16.10.45      1 Full/DROther      36.319s 10.255.13.29    gre1:10.255.13.30      247     0     0

but I have no ospf routes:
K>* 0.0.0.0/0 via 2xx.x.x.1, vr1
O   10.254.150.0/24 [110/10] is directly connected, vr0, 00:00:14

C>* 192.168.198.0/24 is directly connected, vr3
C>* 2xx.x.x.0/24 is directly connected, vr1

In my ospfd log I see a continual stream of the following type of message:

Any ideas on what to look for?
This had been working and no config changes were made on the quagga end.

Thank much,
Steve
